Whoa there. Are you seriously gatekeeping sci-fi? Don’t be a jerk.
Just the MCU characters with an obvious sci-fi backstory: Tony Stark, Hulk (an actual scientist), everyone in Guardians of the Galaxy. Even Thor is actually an alien using Sci-Fi tech. Bucky Barnes is a cybernetic super soldier. There’s the Nazi scientist from Hydra that transferred his consciousness into a computer. Fucking Vision and his love story with Wanda. Black Panther may mix in some mystical drug, but his suit and all the other toys are all science fiction.
I’m not arguing that ANY of these are great science fiction stories, but they are still undeniably science fiction. Sci-fi stories are often also something else: horror, action, humanist, dramatic, comedy, or all of the above.
Not every science fiction story needs to use the obvious sci-fi tropes either. Ursula K Le Guin wrote a bunch of very influencial science fiction stories that you could be forgiven for classifying as fantasy and have very little shiny tech in them.
Wow, what a dumb and toxic take.
